        Use an XPath string to select a nodelist. XPath namespace prefixes are resolved from the namespaceNode.
        Specified by:
        selectNodeList in interface XPathAPI
        Parameters:
        contextNode - The node to start searching from.
        xpathnode -
        str -
        namespaceNode - The node from which prefixes in the XPath will be resolved to namespaces.
        Returns:
        A NodeIterator, should never be null.
        Throws:
        javax.xml.transform.TransformerException
